Abstract
A comfortable acoustic environment in residential and public buildings is an important task that can be solved only in a complex of special constructive measures, one of which is to improve the sound insulation of enclosing structures, including floor-to-floor ceilings. The article presents the results of laboratory tests of building materials used as elastic gaskets when installing floating floors. The compositions of floating floors are described, graphs of the frequency dependence of the improvement of shock noise insulation by tested structures, as well as their single-digit characteristics are given.
